MATERIAL-WORKING MEOHANISM.

Application led December 20, 1924. Serial No. 757,280.

rlhis invention relates to material working mechanisms, and more particularlyV to a continuously operating strand reeling mechanism. A continuously operating strand reeling mechanism to which the -invention is espe- `cially applicable is` disclosed in Patent No. 1,393,286, issued October 11, 1921 to W. F. Hosford. i f l in a material working mechanism. wherein the material is received in a predetermined length on a reel an improved means for changing the length of material to be received on the take-up reel.

Another object of the invention is to rovide in a continuously Operating zree ing mechanism, whereinmaterial` is received upon a plurality of reels successively `associated withv the sup lyof material, means to selectively vary t ciation periods. l s .l

In accordance with the general features of the invention, a planetary gearingsystem is provided in a reeling `machine which drives a `strand transferring andisevering mechanism, causing it to function at regular predetermined intervals to operatively associateja reel. with the supply andlsever from 3o the supply theportion of strand wound on another reel. A manually Operatedcontrol gear is "included in the system of gearing whereby the speed of the timing wheel asso v1e lengths of the associated with the strand transferring andsev ering mechanism'may be readily changed while the mechanism is in fulloperation to vary the lengths of the predetermined `intervals between the actuations of the 1 transfer-ring and severing mechanism. The transferring and severingV mechanism may also be reset to its startingposition by means ofithis gear shoulda break Occur in thestrand, and

-thusa new reel may be operatively associated with the` supply at the end where the break occurs.

1 Other advantages of `the invention .will more fully appear from the following detailed description takenin connectionwith the accompanying drawings, `in `which Fig. lisa side elevation `of a reeling machine'of the type ldisclosed in the hereinbefore mentioned patent andembodyingthe features of thisinvention;

Fig. 2 is a fragmentary Arear view thereof; Fig. 3 is `an enlarged vertical section taken .An object of the invention `is to provide Vwound `on the first reel.

.an the une ame 0f Fig. 2' f the adjustable control device which comprises the inven-v tion, and Figml, is a section taken on the line 4-.-4 of Fig. 3 partly broken away to show some of the arts more clearly.`

In lli y numerals designate like parts throughout the several views a reeling machine 10 of the type described and illustrated in thehereim before mentioned Hosford patent is shown mounted on a base 14:. As fully described in the hereinbefore mentioned patent, the various operating elements of the reeling machine 10` are driven by suitable gearin from a shaft 15 which in turn is connecte `by suitable gearing (not shown) with a shaft Vpassesbetween a pair `of distributing fingers `113 andlll: mounted on a curved arm 112, to

one of a pair'of take-up reels 217, 218. VWhen ,a predetermined amount of strand material has been wound on` oneof the take-up` reels 217, 218 thelingers 113 and 114 serve to transfer the strand from the full reel -to an empty reel. At the `same time mechanism `indicated at 219 causes a rocker ar1n117 to rotate in aslot 221 ofthe timing wheel 220,

which movement will` shift the curved arm 112 from the full reel to the empty one. `In thisshifting movement theY strand will `be .caught byone of the lingers 89" of the disk 88 associated with the reel on which the 4strandhas been wound, stretched across `the 'space intervening between `the two reels,and then caughtby another finger` onthe disk associated with theempty reel on which the strand istobe wound. As the reels continue `to rotate thestrand is guided between the two disks 88 into the path of the knives, indicated at 90, lwhich rotate about the shaft 95 at the bottom of the machine.

4The strand will'therefore be cut by these `knives and the oncoming strand will be disconnected from thev` strand which has been The strand will now be wound on the second reel and in the continued rotation of the timing` wheel the arm 112 will be shifted from a wound reel toan empty one. It is believed `that this -brief description of the operation of a cone` drawings in which like reference tinuously running reeling machine is soilicient, but for a more detailed description of euch a mechanism reference may he had to the hereinbefore mentioned patent to Hosford.

In the timing mechanism indicated at 219 (Figs. 3 and 4) the timing wheel 220, which is slotted at 221 to admit the rocker arm 117, is rotatably mounted on a shaft 223 which is supported in brackets 222. Secured :to the timing Wheel 220 by stud screws 224 is an internal gear 225. A worm gear .226 is also suitably keyed to the shaft 223 and .is driven 'Lby a worm 227 formed on a .shaft `230. A .son gear 228 is ysecured to the worm gear 226 by stud screws 229. Rotatably 'mounted on the shaft 223 between the timing Wheel l220 and the Worm gear 226 is another worm gear 231 which is the control gear and isv ydriven `by a control worm 232 formed von a shaft 233. The control worm 232 also serves to lock the control gear 231 when the ltiming mechanism is functioning Lin regular predetermined intervals. A shaft 234 is rotatably `mounted in bearings 235 which are secured to the control gear `231. Keyed to oneend of the shaft 234 a pinion or planet gear 236, .which meshes with and rides around Athe `sun gearV 228. Another pinion gear 237 is keyed to the .other end' of the shaft 234 and meshes with the internal gear 225. Itis obvious that when the -mechanism indicated at 219` is `functioning at .regular predetermined intervals V-the control gear 23-1 is locked .and the internal; gear 225 is being driven by the pinion lgear 237 which revolves .with the pinion gear :236, and in turn the pinion l236 is driven by the sun gear 228 which is secured to the worm gear 226 driven by the..worm 227.

Keyed to the end of 'the shaft 233 is a hand wheel 240 Vwith Whichthe operator controls the mechanism. AAlso4 keyed to lthe shaft 233 is a Ygear 241 Ywhich meshes with a ygear 242 rotatably mounted on the shaft 230. A clutch indicated at 255 consists of a vratchet member 245, slidably mounted on a slotted portion 240 of the shaft 230, which may engage a ratchet portion 246 kformedinte ral with the gear 242. Pivotally vmountedg'in a bracket 24'7 secured to the frame 14 is a shifting lever 248 having a `forked end 1249 which engages an .annular groove .250

oiating another reel with t determined amount ofstrend material to be wound on` the take-up reel before the severing mechanism is actuated and while the machine is in operation, it is necessary to stop, or yat least' decrease the Speed of the timing wheel 220. This is done by turning the hand, wheell240 to rotate the control gear 231,` which Acarries the shaft 234 and the `pinions 236 and 237, in the same direction as that in which the timing Wheel 220 rotates. The. :pinion gear 236 will rotate `around lthe sun gear 228 .and the pinion gear 237 .will `rotate in the internall gear 225, thereby neutralizing the motion ordinarily imparted; t0 fthe timing Wheel 220 4by the lworin gear 226` andustopping the rotation of Vthis `wheel or reversing its direction 4of rotation according vto the speed imparted to the control ear 231. This will cause the severing mec anismto :Actuate after more than the voriginal .prcdetcriznined amount of strand has been wound, ythereby permitting a .longer coil of strandpto be. wound.

. Should a ,break occur in the strand 'the timing wheel 220. can :be reset .to .the starting position :in the above described' manner ,and a new reel oit' strandrstarted at the point .of the break.

To continuously ivindistrand'material on thetake-.up reel the yclutch 255 is engaged. The gear 241 isjhen driven by .the shaft 230 and with the ear 242 forms a differential Wihiebdrives t Ae ,controle ear 231 ,at a speed rthatstom YTo discontinueA the abone operation the clutch 255 `,is released allowing .the timing whee1220-tp vvrevolve .and the severing.mechanism to `act-u- `'llo decrease the predetermined length of :the coil ot strand; being Wound on the takevupreel thecontrol gear 231 is rotated bythe `hand ,wheel; v241), rin `an opposite .direction to that which the .timing `wheel 220 rotates.

Thisowill turn the timingwheel V220k at .an additional speed and the wire severing mechanism .will actuate befolae the ,original :predetermined amount of strand has been wound; .v
